OuBlog is an activity that allows everyone in a course to post to the same blog, groups to share a blog, or individuals to keep a personal blog. Options include allowing comments, grading, adding searchable tags (keywords) and adding attachments.
OU Blog vs. Forum – OU Blog is a better choice when posting is the main purpose, rather than replies or a back and forth discussion. All blog posts appear on one page, so it is easier to view than some forum types. Each post can be a new topic, and the newest posts are displayed at the top.
